National spending for hospital care grew just 0.8% over the 12 months that ended in June, the lowest rate since at least January 1989, according to the latest report from Altarum Institute's Center for Sustainable Health Spending. National health spending growth fell to 4.0% for the second quarter of 2017, driven by lower growth in hospital spending. “These lower growth rates have resulted in health spending growth that has been lower than [gross domestic product] growth for each of the past three months, averaging GDP minus 0.3% for May through July,” the report notes.
